Thinkers, What are the reasons for not bypassing the center tap on the push-pull amps apart from high bypass current? There are spikes on the rising edge near the positive and negative peaks in the w
Hello, Everyone, In doing the transmitter checks, a scope with two reliable channels was needed for the ScopeMatch and for troubleshooting. The local TV repair shop is going out of business and sold
Friends, The VY1JA beacon is off the air for improvements and will be back on the air as soon as possible. For now the station is in reception mode. If anything of value is seen an LWL will be sent t
Scott, Sorry, I have been running the single 640 amp of Steve's for a number of weeks now at about 130 Watts input or about 100 W output. It has worked in rain, wind and sun and keeps on going. Becau
Friends, Alan's post makes me wonder if it is possible... As a "consolation prize" daylight paths of 1000 to 2000km, should improve by about 10 dBs on Tuesday and possibly also Wednesday. Any observa
Friends, At about 04:30, KI0LE picked up the weak signals again from QRSS60, 100 Watt, VY1JA during a period of apparently maximum signal strength just before the XES signal died. This is much like w
Laurence, The VY1JA beacon is still on 24/7 ~137778.4, QRSS30. Tonight/Sunday AM, if Steve sees good traces of the beacon, we may try a short CW QSO around 3:00-ish PDT. If you have any traces which
Jim, Thank you for the feedback. I had no idea what the waveforms should look like before your message. Yes, the bypass capacitor is on the supply side of the supply choke and there is none on the ce
Laurence, and Friends, VY1JA beacon is on ~137778.4 QRSS60 ~100 W tonight. Steve is very likely correct, and I do not expect that you will even get a peep from here, but I appreciate that you are thi
Scott, I am sorry that it is necessary for you to repeat things to me. My memory has improved, but still has holes in it. For some reason, I keep re-solving the problems instead of remembering the co
Friends, It was nice to have a full night of reception of the VY1JA beacon on the TIL Grabber when no LORAN were received and interesting to see that only for a few minutes, the propagation leaking i
Friends, VY1JA beacon is ~137778.4 QRSS60 ~100W TX output. CP20kw Again, reports, comments or captures are appreciated. Rapido is set to capture the KI0LE and VE7TIL grabbers. These are about the exp
Friends, Scott's amp is on at VY1JA. It will need to be hooked up to the relay and will need the SWR protective circuit added, but for now it is going. If you see any blips in the band it will likely
Friends, The transmitter I have borrowed from Steve, works 24/7 and has an excellent output wave form through the scopematch on its way to the antenna. This amp uses a single layer solenoid transform
I would like to thank those who sent their kind condolances. Ann and I returned yesterday. Failures in beacon transmission were found to be computer related. The station computer failed and an old De
Rik, It looks like I have made wrong assumptions again. I am sorry if my words offended you in any way. The strong support for you and QRS that has been displayed has encouraged me to get an old lapt
Rik, One more item.... It worked well that way also. For some reason it does not like switching from sending QRSS60 to 9 wpm. What else may be wrong in my setup? J.
Hello All, Tonight, I notice that the "JA" (VY1JA) signal is the strongest it has been into MN on the KI0LE Grabber. If there are any reports, or captures, even partials, please send them to: vy1ja@n
Hello Friends, The first traces of a "mystery signal " are appearing on a slightly different frequency tonight. 137699.25 Also, today propagation is much different, The east coast LORAN is gone and t
